WASHING MAGI-III-IE.

Application filed May @1926, Serial No. 197,153, and in France May 12, 1925.

The object (it this invention is to provide an unprov-cd machine which will buel: or

scald, wash and rinse material by causing ets oi steam and. water. or other boiling liquid lo impinge against the seine. such niachiue being); adapted to treat or wash objects material oi? various mod tications; i

l ig. "Z is a 'l l'z'lfjllltllll'fll vertical cross-section. showing; a double bottom i F 8. 9 and 10 are crosssections oi; douhle bottoms with siphons:

.lr =1 ll and 12 are cross-sectimls oil. double bottoms with valves.

lli l3, 14: and i5 arelongitudinal sections of injection: devices. I

A drum 1 (Figs. 1, 2 and 3) has its surface wholly or partly perforated with holes 2, a ad is also p rovidcd with an openi n g 3 tor the admission of a subsequently-deseribed injector; such opening 3 being; closable at will by means of a door 4, or other suitable contrivanco. 5 indicates the door for the drum. One or more battles 6 of suitable term may be arranged inside the drum and maytheinselves be perforated withholes 7.

The drum is here shown as cylindrical, or substantially so. though it may have any other desired shape. and it is fitted with two trunnions 8 adapted to rotate in bearings or supports 9 rigidly connected to an outer vessol or container 10 wherein said drum is arranged and in which it is rotated by means of a suitable device.

Container 10 which likewise may be of any desired form. is provided with a double bottom 11 that is fixed or removable. This ele- In "it is preferably of conical or concave shape and is perforated at its lower portion with holes 12, while its top is shaped to iiorrn a neck or throat 13 on which is fitted a removable injector l l oifsuitzble form. This injector extends upward to about the upper-portion t tliGCllLUn, and it is provided either at its upper end or at some other point with jet holes or apertures 15,-the top of said 1n ector being closed by a plate or disk 16.

7 r i and (i are similar views of further connected thereto by any suitable means. As

an example, a device adapted to permit such removable attachment has been illustrated, W two or more studs 17 secured to the container near its bottom tl orengagement in inclined slots 18 formed in the peripheral portion Oil the bottom member or cone. In order to in said member in position, it is merely necessary to bring slots 17 opposite studs 18 and then turn it slightly toinalre the studs catch. The aforesaid slots may, if desired, take the place of the holes 12.

The outer vessel or container may be provided with a spout 1.9 tor filling and em purposes, which may itseli be litled V a lid 20 to prevent escape of liquid during operation ot the machine; and said container may also be equipped with handles 21 and with a drain cock .22 and an overflow 23. and may have a cover 24:, the overflow 23 being: closable by asuitable plug or the like. The cover 24 may be provided with handles and by turning it upside down it is rendcred available to receive the material before and. after washing. shown in Fig.1, the handles 25 are so set as to extend in the proper direction when the cover is placed on its bottom.

lljn operation. the outer vessel or container 10 chargedwith the vzshingorotherliquid and then is placed on a suitable heater. The

liquid within the bottonr member or cone 11 soon starts to boil and the steam thereby evolved rises and escapes through the neck or throat lVith the exception of-a very sin all portion, mentioi'ied later on and which escapes through. the openings 12 and 18, no outlet forthe steam other than said neck is provided; in fact, in order to escape through the altoresaid openings it would be necessary for the steam to lower the level of the liquid in the cone by torcing it 'far enough down to uncover sa d openings which are normally sealed by the liquid and to do that it would c to overcome the pressure of the column of liquid a. The steam which can escape through openin s l2 and 1.8 is merely the smallanion. "hit-h is produced directly be heath or in the immediate v cinity of these 7 10's; and such amount does not inter open f re h the or ation of the llltlCllll'lQ, being.

l llttiitdin 2 .sce1'1ds, as shown, through the cone throat 1.3 into the injector 14, carrying \vithjitpart of the liquid. This nnxture t steam andliquid, on reaching the top plate 16 .01" the injector, is discharged into the drum through the apertures or jet holes and spreads or expands into the form of a curtain 0 which showers upon. the material under.

the drum. 7 Replacing'the liquid just evacutreatment and werks its way therethrough, finally escaping through the lowerholes 2 of ated from the cone, some liquid enters the lat ter from outside through the openings 12 and 18 and, tLlWEtjf-SHllXQil with steam, is 1rried along, in its turn, through the partslS andl tand is ultimately sprayed thioughapcrtures 15. 1

' According to the. activity of the boiling, the spraying Orsprinkli-ng is either intermittent or continuous; but in any event it will be apparent that the soaking of the material, especially in the caseof linen takes place in the manner usual in an ordinary fvvashing machine, even though the openings for readnutting the liquid, into the cone are not partly already undergone I a.

stopped up by the material. The arrangement of the parts, as above described, prevents any scorchii'ig o'l zthe material, since it is contained in drum 1 which is itself partly submerged in the liqui'd,so.that it can never come into direct contaetwith the heater. The drum may, of course, be perforated over its entire surface.

At the completion of the operation, it is merely. necessary to detach injector let from the coneneck or throat 13, after having first removedcoverfli and opened charging door 5, then close said door and, after having turned the drum through a half-revolution, theinjector door 4t,'and then rotate the drum; such rotationpreferably being carried out first in "one directionand then inthe other for a few revolutions; During rotation, the battles 6 in side the drum will pick up the material and then drop it'b acl; into the liquid so that Washingfis rapidly effected; the washing being further facilitated. "in that the material has bucking or scalding treatment and can bev washed immediately thereafter, before it has had time to cool, and

even in the scalding liquid itself. Moreover,

the rapidity of the washing can be increased still further byleavmg' the machine on the I heater, so that the cone neck 13 will then serve I an injector, stirring up the liquid and actrvatmgth'e treatment;

. "F or, rin,sing, 'tl1ewvasliing. liquid is dis:

charged through drain cock 22, and rinsing with.

liquid is admitted through spout 19, whereafter the drum is rotated for a few moments. The rinsing liquid may be fed in :1 cont inuous stream through said spout and. after serving its purpose, may escape through overflow 23; or its escape may take place, if preferred, either through cock which has first been suitably adjusted to control its delivery) or through both parts 23 and 2:2. entriiuging of the material can be simply cll'cclcd by discharging the liquid through the drain cook, which is then left open, and rotating the drum rapidly for a few moments, the liquid contained in the material being driven out through the perforations 2 oi the drum and falling into the outer vessel or container 10, whence it is discharged through the drain cock. These operations can, of course, be carried out without any handling of the material, as will be apparent; and it is advisable, during them, to keep the container closed in order to minimize heat losses and to avoid. projection of liquid, especially during centrifuging.

It is to be noted that the machine above described may be used. if desired. solely as a bucking and scalding machine. either by puttingthe material to be treated in drum 1, as set forth, or by removing the drum and putting the material directly in container 10 as is usual in ordinary scalding machines. In the latter case, a perforated false bottom or screen 26 (Fig. 7) may be supported fixedly ordetachably in the container in any suitable manner so as to keep the material a distance away from the bottom of the container in order to prevent it from being scorched, the presence of this screen entailing no change in the opera.- tion and offering no interference therewith. Furthermore. on removing the injector l4, and the cone 11 well. i l desired. the material can be placed in drum 1 and the latter then rotated in hot or boiling liquid, like an ordinary washing machine.

Figs. 4. 5 and 6 of the drawings show various other forms of bottom members and injectors which can be used. In Fig. 4, the bottom member 11, instead of having the shape of a cone,is formed by an inclincd plate. with at its upper side.

athroat or tubular stem 13 The injector 14. which removably telescopes over said said throat at its lower end, is so bent or shaped as to extend part way around the drum. sprinkling or spraying taking place through the jet apertures 15'. The charging door-.5 is removed. of course, to permit the injector end to project into the drum through the door opening andthus permit the sprinkling action to take place. and the door or gate t and the injector opening 3 are done away Rotation of the drum merely requires thedetachment of the injector from throat and the subsequent closing of the charging oor.

In the construction represented in Fig. 5, a conical or approximately conical bottom 11 is used, having an inclined central stem or throat 13 for eoaction with an injector 14 bent similarly to the one in ll l. The tree terminal portion'ojt this injector-projects horizontally entirely across the charging); door opening and pertoratod longitli'dinally along its under side as at l, sprinkling taking place through these pert irations instead of at the end or tip of the in ector. The latter can be disengaged ii-om throat 13 and re moved, and the charging door then closed when it .is desired to rotate the drum,

6 shows a further modification in which a conical bottom niember ll is employed having a frusto-conical tin-oat or stem 13, while the drum is provided in its circumierential wall with a tapered sleeve or soche 527 which is rigidly secured in an opening thereinand carries a grating or screen 28 at its inner end. A tubular injector l/l similar to that 01" Figs. 1-3, is removably titted over throat I3 but the gate or door 4 is omitted. The steam and boiling liquid escape from the cone 11 and pass into andv throiigh the socket 27 and its grating and the injector 1r, spraying taking plat-eatthe top of the injector at as in the first tl orm, The grating or screen 28 serves to prevent the material under treatment :trom falling out of the drum through socket 27 whilethe drum is being rotated.

As regards the further modifications illus trated. in Figs. 7 to 12, Fig. 7, as has been stated, shows a perforated screen. or grating for supporting the material. Fig. 8 represents an arrangement in which an auxiliary siphon 29, provided with a cap 30, is utilized to increase the siphon etl'ect produced by the injector and the openings 12 in its bottom member ll, as well as to preventfthe escape through said openings at the small quantity of steam which is generated at or nearthe same; in order to do so, such steam would have to lift, through the intermediary oi? the siphons, of which there one for each opening, the whole liquid column a. Fig. 9 shows the use of a bent tube 31 as a substitute for siphon 29-30.

In Fig. 10, a simpler form of siphon device illustrated, according to which the openings 12 in the bottom member or base 1.1 are provided with short depending tubes 32; these tubes, however, not preventing the escape of the steam generated directly beneath them. The openings or opening 12 (for there may be only one such opening if preferred) may be equipped with flap valves 33 (Fig. 11.) or ball valves 34 12) the valves adi'nitting liquid in the direction of arrow (5 but preventing steam and liquid from passing through in the opposite direction. Finally, the bottom wall of the container may be provided with a battle, fixed or removable, as indicated at 35 in Fig. 10, for the purpose of avoiding leakage of steam through any interstices j which may exist between the bottom member or base 11 and the bottom 'wall oil? the container. Such bathe, however, can be constituted by a simple rib formed in or on said bottom wall and designated 36 in Fig. ll. It will be observed irom Figs. jltL-li that the bottom member or base can have a simple convex formation instead of being a true cone.

l i 13l5 show some terms which the injector may take: Fig. it; represents a. tapering tube 145* provided at its top ith a plate 16" that leaves between it and the tube end a space 15 for the discharge of the jets of steam and liquid therethrougli Fig. 1 lillust ates a cylindrical tube ll topped with a mushroom head 16 prov ded with et openings or slots'l5 and Fig. 15, a tapering tube i lterminating in a n'iushroom head 16 having jet holes 15. i

As will now be understood, the machine described and shown is fully adapted for bucking, scalding, washing, rinsing and centrifuging the material to be treated, and all this without said material havingto be removed *lrrnn the machine and without any accessory handling being required. It is particularly well. suited ttor scalding, washing, rinsing and centrifuging linen, the required. lye and soap having, of course, first been. put in the water contained in the machine.

Taking as an example the washing of linen, the following operations can be carried out successively with the machine 1. Bucking (soaking) .--Put the linen in the drum and water in the container so that the linen will. be thoroughly saturated, and let soak.

.9. Sodding-Empty the bucking water, put some water in the container, as well as the usual scalding and. lye-washing ingredients, and then put the machine on a heater and allow it to operate as a scalding machine.
